noPixbufFormat :: Maybe PixbufFormat Source #

A convenience alias for Nothing :: Maybe PixbufFormat.

Methods

copy

pixbufFormatCopy Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m PixbufFormat	Returns: the newly allocated copy of a `PixbufFormat`. Use `pixbufFormatFree` to free the resources when done

Creates a copy of format

Since: 2.22

free

pixbufFormatFree Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m ()

Frees the resources allocated when copying a PixbufFormat using pixbufFormatCopy

Since: 2.22

getDescription

pixbufFormatGetDescription Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m Text	Returns: a description of the format.

Returns a description of the format.

Since: 2.2

getExtensions

pixbufFormatGetExtensions Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m [Text]	Returns: a `Nothing`-terminated array of filename extensions which must be freed with `strfreev` when it is no longer needed.

Returns the filename extensions typically used for files in the given format.

Since: 2.2

getLicense

pixbufFormatGetLicense Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m Text	Returns: a string describing the license of `format`.

Returns information about the license of the image loader for the format. The returned string should be a shorthand for a wellknown license, e.g. "LGPL", "GPL", "QPL", "GPL/QPL", or "other" to indicate some other license. This string should be freed with free when it's no longer needed.

Since: 2.6

getMimeTypes

pixbufFormatGetMimeTypes Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m [Text]	Returns: a `Nothing`-terminated array of mime types which must be freed with `strfreev` when it is no longer needed.

Returns the mime types supported by the format.

Since: 2.2

getName

pixbufFormatGetName Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m Text	Returns: the name of the format.

Returns the name of the format.

Since: 2.2

isDisabled

pixbufFormatIsDisabled Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m Bool	Returns: whether this image format is disabled.

Returns whether this image format is disabled. See pixbufFormatSetDisabled.

Since: 2.6

isSaveOptionSupported

pixbufFormatIsSaveOptionSupported Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> Text	`optionKey`: the name of an option
-> m Bool	Returns: `True` if the specified option is supported

Returns True if the save option specified by optionKey is supported when saving a pixbuf using the module implementing format. See gdk_pixbuf_save() for more information about option keys.

Since: 2.36

isScalable

pixbufFormatIsScalable Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m Bool	Returns: whether this image format is scalable.

Returns whether this image format is scalable. If a file is in a scalable format, it is preferable to load it at the desired size, rather than loading it at the default size and scaling the resulting pixbuf to the desired size.

Since: 2.6

isWritable

pixbufFormatIsWritable Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> m Bool	Returns: whether pixbufs can be saved in the given format.

Returns whether pixbufs can be saved in the given format.

Since: 2.2

setDisabled

pixbufFormatSetDisabled Source #

Arguments

:: (HasCallStack, MonadIO m)
=> PixbufFormat	`format`: a `PixbufFormat`
-> Bool	`disabled`: `True` to disable the format `format`
-> m ()

Disables or enables an image format. If a format is disabled, gdk-pixbuf won't use the image loader for this format to load images. Applications can use this to avoid using image loaders with an inappropriate license, see pixbufFormatGetLicense.

Since: 2.6
